The banking firm : the role of signaling with collaterals

In this paper we challenge basic results of signaling models. In our banking model each project of a borrower is described by a continuous density of outcomes. Different density functions are classified according to second stochastisch dominance. Combining these features we find that in a banking model collateral is no longer in a position to signal the degree of riskiness of the borrower to the lender. In most cases the equilibrium is a pooling equilibrium. -- Signaling ; collateral ; perfect Bayesian equilibrium
